摘要
为了解决室内定位不准确、成本高、安装不方便等问题,提出了一种基于AT86RF233相位差测距的二维定位系统。系统由上位机、网关、基站、协调器、终端五部分组成,通过测量4个基站到终端的距离实现定位。由C#编写的上位机软件控制定位的启动和停止,执行定位算法和在一个图形界面上实时显示终端的所处位置。实验表明本系统具有部署简单、低成本、定位精度较好等优点。
To solve problems like inaccuracy, high-cost and inconvenience of installing in indoor position system, a twodimensional indoor position system based on AT86RF233 of phase difference measurement is designed. The system consists of five parts： upper computer, gateway, base station, coordinator and terminal and it can realize the positioning by measuring the distance between four base station and terminal. The upper computer software compiled by C# controls starts and stops of location, executes position algorithm and displays real-time location of the terminal on GUI. The test shows that the system has the advantages of simple deployment, low cost and good positional accuracy.
